A man going to extreme lengths to get out of paying a traffic ticket claimed falsely that he was a captain of a volunteer ambulance company rushing to an emergency in Bed-Stuy, authorities said.

John Warwick, 47, allegedly blew through a red light at Atlantic and Kingston avenues at 1:30 p.m. last Dec. 14.

Rather than pay the summons, Warwick allegedly presented documents at a March 13 hearing indicating he had been responding to an emergency call for the Bedford-Stuyvesant Volunteer Ambulance Corps.

However, the organization’s commander told investigators that Warwick holds only an honorary title and performs administrative tasks, court records state.

Warwick was arrested on Sept. 6.
